Key features
  • Time, CPU & memory profiling
  • Async observability for futures, channels and streams

  • HTTP calls profiling for reqwest and ureq
  • HTTP server profiling for axum routes
  • Concurrency metrics for Mutex and RwLock
  • Tokio runtime monitoring
  • Prometheus & Grafana integration
  • CI regression detection with automatic benchmarking
  • Real-time tokens per second display in status bar
  • Request wait time tracking
  • Cache hit rate and context size metrics
  • Codex rate limit usage tracking
  • Live terminal session table
  • Works with any model the agents run
  • Offline operation, no network requests
  • Integration with Claude Code status line
What makes it different
  • No overhead when disabled—all macros compile to no-ops
  • Deterministic instruction counts with Callgrind for stable CI regression checks
  • Instruments real applications with real workloads, not isolated benchmarks
  • MCP server for AI agent integration
  • Live TUI dashboard and static reports
  • Works offline with no API key required, reading only session logs on your computer
  • Integrates into VS Code status bar, Claude Code status line, and terminal
